SpecificationS
Range: -58 to 2372 °F
-50 to 1300 °C
Resolution: 0.1° or 1° (selectable)
thermocouple
The sensor supplied is a stainless-steel Type-K
probe. Maximum temperature for this sensor
is 446 °F (230°C). Accessory thermocouples
are available for measuring temperatures
throughout the entire range of the unit (See
“Accessories”). Only Type-K thermocouples
may be used with this unit.
Longer leads and extensions may be used.
The lead effect for 164 feet (50 meters) is
generally less than 0.2 °C with a limit of error
of 2.2 °C. Type-K wire and connectors must
be used.
operation
Insert the thermocouple plug into the socket
located on the front of the instrument. The
plug and socket are keyed with a small and
large pin. Make certain the plug is inserted
correctly, do not insert the plug incorrectly and
force it.
Press the POWER button to turn the unit on.
Pressing the °F button will display the tem-
perature in Fahrenheit (°F will appear on the
display). Pressing the °C button will display
the temperature in Celsius (°C will appear on
the display).
Press the 0.1° or 1.0° button to select the
desired temperature resolution. (Note:
0.1° resolution can only be used when the
temperature being measured is between -50°
and 199.9°)
Place the thermocouple in contact with
the material to be measured and read the
temperature on the display.
Press the POWER button to turn the unit off.
To conserve battery life, always turn the unit
off when not in use.
holD
Press the HOLD button to “freeze” the display
at the current reading (“H” will appear at the
top left corner of the display). Press the
HOLD button again to return to the current
reading.
offSet aDJuStment (fine tuning)
By adjusting the offset control, found on the
front of the unit, the measurement accuracy
may be optimized for a particular thermo-
couple at a particular temperature.
While offset adjustments are possible
they will VOID with the factory calibration.
This unit has been calibrated Traceable ® to
standards provided by the National Institute
of Standards and Technology (NIST).
Traceable ® recalibration must be made by
the factory (See the “Warranty, Service or
Recalibration” section).
bench StanD/wall mount
The unit is supplied with a bench stand that
is on the back of the case. Locate the stand
on the back of the unit. With your thumb
and forefinger, lift the stand out. To close the
stand, simply snap it shut.
The unit may be wall mounted by using a
screw. Set the screw into the wall at the
desired location. Do not set the screw flush
to the wall, the head of the screw will need
to slip into the receptacle on the back of the
unit. Hang the unit by sliding the receptacle
located on the back of the unit over the head
of the screw.

all operational DifficultieS
If this unit does not function properly for any
reason, replace the battery with a new high
quality battery (see the “Battery Replacement”
section). Low battery power can occasionally
cause any number of “apparent” operational
difficulties. Replacing the battery with a new
fresh battery will solve most difficulties.
batterY replacement
Erratic readings, faint readings, no display
or a battery symbol appearing on the display
are all indications that the battery should be
replaced. Before replacing the battery, turn
the unit off and unplug the probe. Remove the
battery cover screw located on the back of the
meter and lift off the battery cover. Remove
the exhausted battery and replace it with a
new 9 volt alkaline battery. Replace the
battery cover and tighten the screw securely.
